Patent FR-2509088-A1 (FR)
Title: Unite de contact electrique en materiau semi-conducteur, dispositif de commutation a commande optique utilisant cette unite et systeme de commutation de telecommunications a dispositif de ce type
Inventor: STERLING HENLEY FRANK
IPC: C07C43/303
Filed: 1982-07-02
Abstract: L'unité de contact opto-électrique conforme à cette invention est un filament de matériau semi- conducteur 11, notamment du silicium, portant des grains de contact électrique 12 et une jonction p- n 13 court-circuitée, par exemple au moyen d'une région métallisée. Ce filament est monté comme une lame encastrée à l'extrémité opposée aux contacts 12 et à la jonction 13, par exemple dans un boîtier de commutateur 21, 25, et soumis à l'action d'un champ magnétique permanent HB, au moins dans la région de la jonction. La flexion du filament pour établir des connexions électriques entre ses contacts 12 et des contacts fixes associés 23 prévus dans le boîtier est commandés par un signal optique dirigé sur la jonction 13, par exemple au moyen d'une fibre optique 26 traversant le boîtier, de sorte qu'un photo-courant parcourt la boucle de court-circuit et interagit avec le champ permanent HB. Un aimant permanent à champ intense pour de très faibles dimensions, constitué notamment de terres rares, est utilisé de préférence pour produire ce champ HB. Application principale à la commutation des télécommunications.

Title: Vehicle headlight with serrated lock - has two parts held together by locking piece fitting into serrated lock in manner of ratchet
Inventor: DAUMULLER HANS
IPC: B60Q1/068
Filed: 1983-04-29
Abstract: The headlight has a locking device that holds its two parts together and consists of a locking piece that fits into a lock with a frame. The locking piece has serrations that cooperate with similar serrations on the lock in the manner of a ratchet. The lock is held away from the frame by a spring arm.

Patent FR-2547837-A1 (FR)
Title: Device for selecting multiple weft threads with a single insertion nozzle for air jet-type weaving machines
IPC: D03D49/70
Filed: 1983-06-24
Abstract: The invention relates to a fixed device for selecting multiple weft threads for air jet-type weaving machines. This device consists of a piece called a positioner 1 including as many convergent passages 2 as there are weft threads which can be selected, each of them being passed inside one of these passages. This device furthermore includes a piece called an accelerator 3 into which a jet of air is sent, which piece may be fixed, if necessary, upstream of the positioner. It includes as many passages as the positioner. Downstream of the positioner there are shears 7. Upstream of the positioner, or of the accelerator if mounted, is a system of grippers 8 such that there is one pair of grippers at the entry to each passage. Selection consists in ungripping the chosen weft thread so that it can insert itself into the nozzle, under the effect of the partial vacuum which results from sending into this nozzle the air jet provided by the constructor of the loom for inserting the weft. Once insertion has finished, the weft is gripped again. If the weft inserted is the last one of the selected colour, the weft is cut by the shears 7 in order to clear the passage of the nozzle.

Title: Needle valve gas stopper for the supply circuit of a draught beer installation
IPC: F16K31/22
Filed: 1984-01-25
Abstract: Device allowing the stopping of the gas used for propelling the liquid when a beer or lemonade barrel is completely empty. It is constituted by a plug 1 screwed on the body of the cylinder 2 for the insertion of the float 3; a seal 4 provides fluid-tightness; a bleeder 5 allows air or gas to be eliminated for the correct functioning of the float 3 when the circuit is brought into service. Two pipes leave from the body and from the bottom of the cylinder 2, one 12 for supplying the beer, the other 6 for the outlet of the beer going to the bar tap. A bowl 8 machined at 90 DEG serves for receiving the stopper needle valve 9 which is at the base of the float 3. When the cylinder contains no more liquid coming from the barrel, the float 3 descends in order to stop the output of the pipe 10 under the pressure of the gas which is still present in the barrel. A part 11 cut from bar is used for removing the float 3; the plate 13 is used for mounting the device. Device according to the invention particularly intended to cut off the gas coming from a pressurized beer or lemonade barrel when the latter is empty of liquid.
